How to get maintiance required light off the control panel of a Honda Odessey.
 

Help please!? I have tried everything requested of me, such as taking the negative post off the battery for a few minutes & reattaching. The light just will not go off. Engineers must put this in so's the dealer will have to use a hand held equipment & charge an arm & a leg to take it off after having the oil changed. Know there is some simple asnwer to this but it escapes me.

Dee Da Dee get it maintenced
